FREQUENTLY ASKED QUESTIONS

How long does a closed terrarium last?
A well-built closed terrarium can last for years — even decades — with virtually no maintenance. Once sealed, it creates its own water cycle: moisture evaporates, condenses on the glass, and waters the plants again.

Do I need any experience to build a terrarium?
None at all. Every kit includes full printed step-by-step instructions. The plants we include are chosen for their hardiness and suitability for sealed environments. Most customers complete their build in 30–60 minutes.

How much light does a closed terrarium need?
Bright, indirect light is ideal — near a window that doesn't get direct harsh sun. A north or east-facing windowsill works perfectly in most UK homes. Avoid placing directly in strong sunlight, as the glass can magnify heat.

Do closed terrariums need watering?
Rarely. A properly sealed terrarium recycles its own moisture. You may need to add a few drops every few months if the glass looks completely dry inside. Consistent condensation on the glass means it's perfectly balanced — just leave it.

What plants are included?
We handpick 3 tropical plants suited to closed terrarium conditions — typically fittonias, peperomias, ferns, or mosses. Exact varieties depend on availability, but every plant is carefully selected and in excellent health.
